Simulation model of the step-up DC-DC converter with auto-transformer and the results of the analysis of operation modes

This article discusses the step-up model of DC-DC converter with auto-transformer (2C2-AT). The simulation model of this circuit was created. The results of properties investigation of the proposed DC-DC converter and its application in spacecraft were presented. Also, the converter operating mode analysis for different values of the input inductance and transformer leakage inductance was performed.
